(Updated with comment from Capitol CannaShow and clarification of Ashby Henderson’s role in Women Grow D.C.)

D.C. is famous for its high number of consultants, and surprisingly, the Capitol CannaShow—hailed by organizers as the “first locally sourced business summit” for the cannabis scene—was no exception.

Around 60 exhibitors showed off their wares on Saturday at the historic Mayflower Hotel, where the purple grow lights glowed beneath the chandeliers and gold-painted molding, as songs like “Uptown Funk” played and organizers read raffle numbers over the loudspeakers. The attendees could go to a number of workshops and panels as well. While many of the 2,000-strong crowd wore Mardi Gras-style weed necklaces and other typical “stoner” garb, many of the attendees seemed otherwise straightlaced and represented a bevy of ages, races, and interests.

“I think the residents of D.C. are finally accepting what’s going on. I mean, we’re in the Mayflower,” says Jamal Verdun, who works with Kuli Vaporizer. “That speaks volumes.”

It’s been a year since Initiative 71 made marijuana legal in D.C., though it differs from legislation in states like Colorado and Washington, where the sale of recreational marijuana is legal. That’s not the case for D.C.’s law. While it is legal to “possess, use, purchase, or transport marijuana weighing less than two ounces” and to grow up to six plants, three of which can be mature at once, selling marijuana remains illegal. Exhibitors at the Capitol CannaShow demonstrated how the cottage industry around Initiative 71 has evolved to accommodate its particularities.

That means that a bevy of hydroponic consultants and educators were there, rather than the dispensaries you might find in a Colorado expo. These services offer to install grow plants for D.C. residents and to check up on their maintenance, or to teach people how to do it themselves. In the case of Capsterdam University, job placement services follow the classes.

It also included organizations like Women Grow D.C.—a local chapter of a national organization, which co-chairwoman Ashby Henderson says wants to encourage “an entry point for women in the cannabis community. We need safe entry points for something that was illegal for so long.”

Henderson also creates coloring books under the pen name Ashby Love. “I get stressed out because I’m not good at staying in the lines, so I made my coloring book big. I think cannabis is important in de-stressing, too,” she says. “Do you ever drive around here? After that, you need a coloring book and a joint.”

Indeed, many vendors talked about their passion for the burgeoning industry. Bri Blair, the founder of Hunnii B Sweetz, which makes edible marijuana-infused candies, says that her business “started with me wanting to bake. I love baking.” She brought free samples of her wares, which quickly ran out. Her challenge has been figuring out how to distribute the candies while remaining in the letter of the law. She says she throws parties where she serves the treats.

Perhaps D.C.’s most famous purveyor of marijuana edibles, Nicholas Cunningham, the owner and founder of Kush Gods, was also at the Mayflower. He was handing out flyers touting the business’ new effort to find a cure for breast cancer. He will be in court tomorrow for another hearing regarding his distribution of marijuana charges. Cunningham maintains that his “donation-based” business model is legal, and says that the business just signed its first model and a new musician to release original music.

But according to representatives from the Capitol CannaShow, Cunningham was not welcome at the event. “The event that I had thrown was about cannabis advocacy and education. Right now I feel like Kush Gods were more about representing their own brand than the community, so I asked them to leave,” says Sumit Agarwal, organizer and founder of the Capitol CannaShow.

The conference offered every possible accoutrement for marijuana as well—vaporizers, bongs, bowls, apparel, papers, and more. Attendee Troy Hudler says he came “‘cuz I like weed.”

And there’ll be more events just like it coming down the pipe. “Stay tuned,” Agarwal says. “Capitol CannaShow Two is going to be even bigger and better.”
